Software Interface 49
OP
This field contains the operation code that identifies the command as the
LOAD command. The OP code for the LOAD command is 0.
Status
This field contains status information about the execution of the
command. The module writes values into this field that indicate whether
or not the command executed successfully.
Offset
This field contains the offset half of the 80186 address where the
command data block is placed.
NOTE
The 80186 processor is a segmented device with the physical
address of a memory area equal to (16 x base) + offset.
The complete address for the command data is segmented into two halves,
offset and base. Only the offset half of the address is incremented during
a load operation. If the size of the data block is too large for the allocated
space at the address, the result of the LOAD command is undefined. If
a LOAD command writes data over memory that is part of the resident
subsystem, the result is also undefined.
Base
This field contains the base half of the 80186 address where the command
data block is placed.
Data[ ]
This field contains the data to be loaded. The LOAD command copies all
the data bytes into module memory starting at the location specified by
the base and offset values. The used field in the buffer header determines
the length of the data string.
